-RECOVERY MEANS FOR MACHINE-CONSTRUCTION DEVICES.

Specification of Letters Patent.

Patented Dec; re, rare.

Application filed November 19, 1915. Serial No. 62,332.

To all whom it may concern:

Be it known that I, GUsTAvE F. LOWE, a citizen of the United States, anda resident of Morristown, in the county of Morris and State of NewJersey, have invented a new and Improved Recovery Means for Machine-Construction Devices, of which the following is a full, clear, and exactdescription.

lid

Among the principal objects which the present invention has in view are:to provide articles of the character mentioned with means for recoveringthe same to prevent loss thereof; to provide a recovery device of simpleand inexpensive construction; and

to provide a recovery device which does not,

interfere with the operation of the element to which it is applied. I

Drawings.-Fi re 1 is aview of a spring band, the ends w ereof areconnected by a screw and nut having a recovery device constructed andarranged in accordance with the present invention; Fig. 2 is a detailview in perspective showing a lock nut and a recovery device constructedand arranged in accordance with the present invention. Fig. 3 is aperspective view of a screw bolt provided with a device constructed in"accordance with the present invention; Fig. 4 isa detail view of akeeper constructed and arranged in accordance with the presentinvention.

, Desmtptoa.-As seen in the drawings, a-

nnt 8 and screw head 9 are each provided with a groovelO for receiving asnap recovery keeper .11.. The keeper 11 has an eyelet 12 formedpreferably as shown in the drawings, by an outward median bend of thewire forming the recovery keeper 11.;

All nuts and screw heads when made in conformity with the presentinvention are provided with a groove within which the said keepers aredisposed either at the time of manufacture or at the time of use.Preliminary to using a nut or screw thus equipped, a cord 13, or otherrecovery device, is secured to the eyelet 12. to be held by the mechanicapplying the nut or screw, or'for attachment to some adjustable part ofthe structure with which the nut or screw is being incorporated.

It will be seen that when nuts or screw heads are thus equipped, theattachment does not interfere with the use of a wrench or other tool fortightening or setting up said nuts or screw heads.

Screws and nuts usually equipped with recovery devices of thecharacter'described, are of such as are employed in constructions whereif the article is dropped, it would be difiicult to recover the same, orwhere if not withdrawn, would damage the moving parts of the machinery.

As shown in Fig. 1 of the drawings, the screw and nut are applied to abrake band usual in the construction of a certain type of automobiles,and disposed therein in a position where the parts are somewhatinaccessible or .difiicult to apply, and where if dropped they fall intoobscure or inconvenient receptacles.

I claim:

The combination of a temporarily removably, rotatively applied devicefor use in machine construction, said device having an annular groove;and a keeper rotatively mounted in said groove, said keeper having anextended portion. for engagement by a flexible recovery device.
